TECHNICAL FIELD

This document relates generally to content distribution and more particularly to providing content to a user based on a user-controllable preference parameter.

BACKGROUND

As Internet bandwidth capabilities increase, on-demand content providing (e.g., video, audio, image content) continues to grow in popularity. A platform's ability to entice users to adopt and continue to use that platform's content providing capabilities is largely based on the platform's ability to consistently provide users with content that matches their tastes. This becomes especially challenging when users' tastes can vary from day to day and even minute to minute, such as based on changing mood, time of day, or other stimulus.

DETAILED DESCRIPTION

FIG. 1 is a block diagram depicting a computer-implemented content selection engine. A content selection engine 102 is configured to provide content items 104, such as music, video, images, or literature, to a user based on a baseline position 106 and a user entered preference parameter 108 (e.g., an adventurousness parameter). The baseline position 106, in one embodiment, is a position on a spectrum of one or more content metrics. The spectrum may be one dimensional or multi-dimensional, as described further herein. The baseline position 106 may be based on user preference. That user preference can be directly entered by the user via a user interface (e.g., the user enters a preferred genre and time period for music), may be derived from user indications of preference (e.g., the user's preferred literary type (fiction, non-fiction), time period (new, classics), and subject are derived from the last n books that the user has “Liked” or otherwise indicated a preference), or may be based on a current content item (e.g., the video type (sit-com, documentary, reality), language, and time period of a current or last video provided to the user).

The preference parameter 108 indicates a user's current preference relative to the baseline position 106. In one embodiment, the preference parameter 108 can be adjusted in real time such that the content selection engine 102 selects a next content item 104 to be provided to the user according to a current setting of the preference parameter 108. In one example, the preference parameter 108 is an adventurousness parameter. The adventurousness parameter indicates the user's preference for a next content item 104 to deviate from the baseline position. Where the baseline parameter 106 indicates adult-contemporary music from the 1980s, an adventurousness parameter 108 value indicating a high degree of adventurousness might result in a 2000s heavy metal song being outputted as a next content item 104. In contrast, when the adventurousness parameter 108 indicates a low degree of adventurousness, the next content item 104 output may be very near the baseline position 106, such as an adult-contemporary 1980s song.

The computer-implemented content selection engine 102 interacts with a content pool 110 to select a next content item 104 to be provided to a user, such as via a computer network or a wireless network. The content selection engine 102 takes the baseline position 106 and the adventurousness parameter 108 into account in selecting a next content item 104 to be provided. For example, when the user enters a low-level adventurousness parameter 108, the content selection engine 102 may select a song near the baseline position 106 (e.g., randomly from a collection of songs less than a threshold distance from the baseline position 106) to be accessed from the content pool 110 and output at 104. Positions of content in the content pool on the spectrum are determined using metadata stored in the content pool 110 as content parameter values. Content parameter values may include a date, a genre, a creator, a sex of a performer, or a content type (e.g., fiction, non-fiction).

FIG. 2 is a diagram depicting an example interface for entering an adventurousness parameter. The user interface 202 takes the form of a slide bar that ranges from not adventurous on the left hand side of the slide bar to adventurous on the right hand side of the slide bar. The user interface 202 can be provided via a graphical user interface, such as for interaction via a mouse, a keyboard, or a touch screen. In another embodiment, the user interface is presented as a physical slide bar (e.g., a physical control on a radio) that enables mechanical hand manipulation and translation of position into a value that can be used by a content selection engine. In the example of FIG. 2, the adventurousness parameter is selectable from a range of values (e.g., from 0.0-1.0; 0-10; 0-100; 0-1000) ranging from an indication of not adventurous to an indication of adventurous. In another example, the user interface may allow a two value Boolean (e.g., 0-1) selection, where 0 indicates not adventurous, and 1 represents adventurous. The content selection engine is configured to select a next content item to be provided to a user based on a baseline position and the adventurousness parameter value inputted by the user, such as via user interface 202.

FIG. 3 is a diagram depicting an example content spectrum associated with content items in a pool of content items. FIG. 3 depicts a one dimensional spectrum 302 that is based on a first parameter. In an example, the first parameter is a video genre parameter. In that example, the spectrum ranges from fantasy at the left end of the spectrum to documentary on the right end of the spectrum. Different genres along the spectrum may be assigned different numerical values (e.g., fantasy=0; adventure=20; horror=40; comedy=60; reality=80; documentary=100). These values can be used to determine distances from a baseline position 304. In the example of FIG. 3, the user has indicated a preference near the midpoint of the first parameter spectrum 302 for the baseline position 304. A next content item provided to the user is based on that baseline position 304 and a value entered by the user for the adventurousness parameter, such as via the interface of FIG. 2.

In one embodiment, the next content item provided to the user is based on the adventurousness parameter value and distances of content items in the content pool from the baseline position 304. For example, a first distance 306 is determined based on an adventurousness parameter value that indicates a moderate level of adventurousness. That value indicates that the user wishes to deviate somewhat from the baseline position 304 but not too much. For example, the first distance 306 could be based on an adventurousness level of 0.4 on a scale of 0 (not adventurous) to 1 (adventurous). Based on that adventurousness parameter setting, the content selection engine is configured to select a next content item having a first parameter (i.e., genre) that differs from the baseline position value 304 by exactly or about the determined distance 306. Thus, the content selection engine will select a next content near one of points 308, 310, such as within a threshold distance (T) from the points 308, 310 that are the first distance 306 from the baseline position 304. In one embodiment, the content selection engine randomly selects a content item from the pool of content item that has a genre parameter that falls within +/− the threshold distance (T) from the first distance 306 points 308, 310.

Should the user turn the adventurousness parameter up to a higher value (e.g., 0.9), content that is further from the baseline position 304 will be selected as a next content item for the user. In the example of FIG. 3, an adventurousness parameter of 0.9 corresponds to distance 312. Based on that high adventurousness parameter value, the content selection engine will select a next content item near one of points 314, 316, such as within +/− T from those points 314, 316. In the example of FIG. 3, this will result in the user being provided a next content item that is near-fantasy or near-documentary, which is far from its baseline position that is closest to the comedy genre. In one embodiment, the spectrum wraps at its ends, such that traversing to the right beyond the documentary genre re-enters the spectrum at the fantasy point on the left of the spectrum.

FIG. 4 is a diagram depicting selection of content by a content selection engine using a two dimensional spectrum. A baseline position 402 is positioned in an upper left quadrant of a spectrum that includes a genre first parameter spectrum 404 running horizontally and a time period second parameter spectrum 406 running vertically. In the example of FIG. 4, the baseline position 402 is positioned near the 1980s time period and the country music genre. In this example, the baseline position 402 corresponds with a current or last content item provided to the user. Thus, the user can use the adventurousness parameter to have a next content item be similar to the current content item or much different.

A first circle 408 is depicted that is a first radius 410 difference away from the baseline position 402. That radius 410 corresponds to an adventurousness parameter value that indicates a relatively low level of user-desired adventurousness. Based on that adventurousness parameter value, a content selection engine will select a next content item for the user that sits at or near the first circle 408 on the spectrum. A second circle 412 is depicted that is a second radius 414 difference away from the baseline position 402. That radius corresponds to an adventurousness parameter value that indicates a higher level of user-desired adventurousness. Based on that adventurousness parameter value, a content selection engine will select a next content item for the user that sits at or near the second circle 412 on the spectrum.

In other embodiments, the spectrum can be three-dimensional or poly-dimensional based on additional content parameter values. Distances from a baseline position can be calculated based on Pythagorean distances along the multiple dimensions. For a three-dimensional spectrum, a particular adventurousness parameter value would be represented in a three dimensional space by a sphere having a radius that corresponds to the particular adventurousness parameter value.

FIG. 5 is a diagram depicting a two dimensional spectrum for use with a Boolean adventurous/non-adventurous-type user preference parameter. A baseline position 502 sits in the lower right quadrant of a two parameter spectrum. A user inputs an adventurousness parameter that indicates either not adventurous or adventurous. If the user selects not adventurous, the content selection engine selects a next content item for the user that falls within the circle 504 having a pre-determined radius 506. If the user selects adventurous, the content selection engine selects a next content item for the user that is outside of the circle 506 in the spectrum. In one embodiment, the pool of content items is segmented based on the baseline position 502 and the circle 504 such that a first portion contains content items that fall within the circle 504 and the second portion contains content items that fall outside of the circle 506. When the adventurous parameter is set to a non-adventurous value, then the next content item is selected from the first segment. When the adventurous parameter is set to an adventurous value, then the next content item is selected from the second segment.

FIG. 6 is a diagram depicting a two dimensional spectrum having a baseline position set based on a center of mass of a plurality of other positions on the spectrum. In one example, the baseline position 602 is positioned on the two dimensional spectrum at an average value on the spectrum for the last n content items 604 for which the user indicated approval. For example, the baseline position 602 may be based on the spectrum positions 604 of the last three content items that the user “Liked.” That baseline position 602 in other examples may be based on all content items that a user has liked, content items that the user has liked in the last x days, or the last n content items that the user has liked, where n is a pre-defined number. Next content items can then be selected based on the baseline position 602 and a user entered adventurousness parameter that adjusts a spectrum radius that dictates from where the next content item will be selected.

FIG. 7 is a diagram depicting a two dimensional spectrum where a next content item is selected based on one or more baseline positions. In the example of FIG. 7, the two baseline positions 702 are indicative of the last two content items provided to the user. The user entered adventurousness parameter corresponds to a distance d, where the sum of the distances 704, 706 from any point of an ellipse (e.g., ellipse 708) is equal to the distance d (i.e., the baseline positions 702 represent foci of ellipse 708). A higher adventurousness parameter value results in a larger ellipse. In other examples, other geometric shapes can be used to define levels of adventurousness from one or more baseline positions.

FIG. 8 is a diagram depicting an adventurous parameter selecting slide bar. In the example of FIG. 8, a baseline position is set as a mainstream setting for the general population (e.g., a top 40 position on the spectrum). By selecting near the left of the FIG. 8 spectrum, a user is provided content near that mainstream setting. The right side of the slide bar is associated with content that is adventurous for the average user. The content selection engine is configured to select a next content item based on that mainstream baseline position and the user entered adventurousness parameter value.

FIG. 9 is a diagram depicting another user interface for entering an adventurous parameter value, where the adventurousness parameter is entered numerically, such as via a keyboard.

For example, FIG. 10A depicts an exemplary system 1000 that includes a standalone computer architecture where a processing system 1002 (e.g., one or more computer processors located in a given computer or in multiple computers that may be separate and distinct from one another) includes a content selection engine 1004 being executed on the processing system 1002. The processing system 1002 has access to a computer-readable memory 1007 in addition to one or more data stores 1008.
